Cross-transport authentication
First Claim
1. An authentication device for use with a portable media device, the authentication device comprising:
- a first connector configured to couple the authentication device to a portable media device, wherein the first connector comprises a first communication port;
a second connector configured to couple the authentication device to an accessory, wherein the second connector comprises a second communication port; and
a controller disposed in the first connector, the controller being configured to;
detect connection of the portable media device to the authentication device;
send a cross-transport request to the portable media device, the cross-transport request including (a) a request for authenticating the first communication port and granting a set of permissions to the first communication port and (b) a request to transfer a sub-set of permissions, from the set of permissions, to the second communication port; and
receive an indication from portable media device that the sub-set of permissions was transferred to the second communication port.

Abstract
An authentication controller coupled to a first communication port of a portable media device is allowed to provide authentication on behalf of an accessory device coupled to a second communication port of the portable media device. In one embodiment, a cross transport connector includes a connector configured to couple with an accessory and a connector configured to couple with a portable media device such that the accessory can be coupled to the second communication port of the portable media device. The cross-transport connector also includes an authentication controller. The authentication controller may request authentication from the media device over the first communication port of the portable media device. The request may also include an identifier of the second port, to which authenticated permissions obtained via the first port may be transferred.

13. An authentication device comprising:
-
a first communication port configured to couple with a portable media device; a second communication port configured to couple with an accessory; an authentication controller coupled to the first communication port and including a processor and a memory, wherein the authentication controller is configured to; send a first message to the portable media device, the first message requesting information about whether the portable media device supports cross-transport authentication; receive a second message from the portable media device indicating that the portable media device supports cross-transport authentication; send a cross-transport authentication request to the portable media device, the cross-transport authentication request including (a) a request for authenticating the first communication port and granting a set of permissions to the first communication port and (b) a request to transfer a sub-set of permissions, from the set of permissions, to the second communication port; receive an indication from portable media device that the sub-set of permissions was transferred to the second communication port; and enable communication between the accessory and the portable media device using the sub-set of permissions. - View Dependent Claims (14, 15)
